What does the word raw mean? What is raw

RAW is an image file.

The raw image file contains data processed from the image sensor of a digital camera, scanner, or motion picture film scanner. They are so named because they have not been processed, printed, or used. Typically, the original image has a wide gamut of internal colors that can be precisely adjusted, and some simple modifications can be made before conversion, such as TIFF or JPEG file format storage.

Facilitate printing, or further processing. These encodings tend to rely on the device of the color image. These images are often described as "raw image files", although they do not actually refer to a single raw file format.

In fact, there are dozens of different models of digital devices that use this format (commonly found in digital cameras or film scanners).

Partial Image Formats:

BMP Format: BMP (Bitmap Format) is the standard Windows image format for DoS and Windows compatible computer systems. The BMP format supports RGB, index color, gray, and bitmap color modes, but does not support alpha channels.

The BMP format supports bit RGB bitmaps.

TIFF format: TIFF (Markup Image File Format) is used to exchange files between applications and between computer platforms. TIFF is a flexible image format that is supported by all drawing, image, and page layout applications.

Almost all desktop scanners can generate TIFF images. In addition, the TIFF format can also add author, copyright, remarks and custom information to store multiple images.

GIF Format: GIF (Image Interchange Format) is an LZW compression format that is used to minimize file size and electron transfer time. In HTML (Hypertext Markup Language) documents on the WorldwideWeb and other online services, the GIF file format is commonly used for realistic indexing of colors and images, with support for multiple image files and animation files.

The disadvantage is that you can only store up to 256 colors.

The original meaning of raw is "raw".

It can be understood that the RAW image is the raw data that the CMOS or CCD image sensor converts the captured light source signal into a digital signal. A RAW file is a file that records the raw information of the sensor of a digital camera, as well as some metadata (such as ISO settings, shutter speed, aperture value, white balance, etc.) generated by the camera.

RAW is an unprocessed and uncompressed format, which can be conceptualized as "raw image encoded data" or more vividly called "digital negatives", and the full name of RAW format is RAWIMAGE format, which is called raw in programming.

There are 3 main benefits:

1. Quality: The raw data directly obtained by the image sensor has the most hierarchical records. Largest Pro Htoto RGB color space.

The format dedicated to digital cameras is a true "electric negative", an undisputed original image. It is the only format for the ultimate quality performance of digital camera images.

2. Later stage: In the early setting, only the ISO and ** amount are correct or not, and the rest can be set and adjusted later. It provides room for adjustment and processing space in the later stage, and becomes the real meaning of the later restoration and re-creation.

RAW is a file format.

The original meaning of RAW is "unprocessed", so the RAW format is an unprocessed and uncompressed format, which can be understood as a RAW image is a optimization model system or a charge-coupled element image sensor, which converts the captured light source signal into the raw data of the digital signal.

RAW file introduction:

It is a file that records the raw information of the sensor of a digital camera, and at the same time records some metadata (metadata, such as ISO settings, shutter speed, aperture value, white balance, etc.) generated by the camera.

Advantages of RAW files:

RAW files are almost unprocessed information taken directly from the CCD or CMOS, and through post-processing, photographers are able to maximize their artistic talent.

The RAW file does not have a white waiter balance setting, but the real data has not been changed, which means that the author can adjust the color temperature and white balance at will, and there is no loss of image quality.

Color linearization and filter row and column transformations are processed more quickly on computers with microprocessors, which allows for the application of some of the more complex algorithms that are not allowed on cameras.

Although the RAW file is accompanied by marker information such as saturation and contrast, the actual image data does not change. Users are free to make personalized adjustments to a single sheet without having to base it on.

1. Two pre-set modes.

Perhaps the biggest advantage of RAW is that it can be converted into a 16-bit image. There are 65,536 levels that can be adjusted, which is a big advantage for jpg files.

This is very important when it comes to an image, especially if you need to make important adjustments to the shadow or highlight areas.
